i tried looking for this part in the GM parts wiki, no luck, only Chevy parts all with the press in dust cap
on my 53 gmc 1 ton, the cap is the press in type, not threaded, so is my 50 1 ton, both trucks are single rear wheel style
would this threaded cap be for the dually 1 ton?
all the photos i find of 49 1 ton's show a press in cap like my trucks
what axle option is this threaded cap from?
do you know for sure it's original?
anyway, calipers and a thread gauge will answer all our questions, straight or tapered and pitch
if you care about originality the wrecking yard is the place to go
